Study on Simulation for Solar Heating System for Biogas

Abstract

The anaerobic methane fermentation is sensitive to temperature, the higher the temperature, the more vigorous microbial activity, higher gas production. Therefore, the temperature is the main factor of methane fermentation. Northern regions due to low temperatures, biogas will be difficult to operate on their own, the need for digester heating. Solar heating is a heating system, biogas fermentation method. Effect of solar heating on the methane fermentation is one of the hotspots in this field. Using MATLAB to provide dynamic system modeling and simulation package Simulink, solar heating methane fermentation system model and algorithm, select the appropriate module on the biogas fermentation solar heating simulation, the method for solar heating in north China to provide a methane fermentation system some new ideas.
